                                50% glucose, also known as D50, is a sterile, hypertonic solution containing 50 grams of dextrose per 100 milliliters, and is a staple in emergency medicine for treating life-threatening low blood sugar. The concentration is critical because it delivers a large dose of sugar quickly and effectively, ensuring a rapid response in patients who are unable to consume glucose orally. Administered intravenously, its high sugar content provides an immediate source of energy to body tissues, particularly the brain, which relies heavily on glucose for fuel.
